FLUID 'DRIJER.

Specification of Letters Patent. Patented Jan, 16]) 11922,

Application filed May 6, 1918. Serial No. 232,972.

To all whom it may concern:

Be it known that I, RAYMOND H. Moonn, a citizen of the United States,residing at Cleveland in the county of Cuyahoga and State of (ahio, haveinvented a certain new and useful Improvement in Fluid Driers, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings. 7

This invention relates to apparatus for drying fluids such as air and,while not limited in its application to any special apparatus, isparticularly useful in connection with sand blast devices wherein thesand is directed against the surfaces to be cleaned by means of airunder pressure and which air should be free from moisture in order toenable the devices and the sand to operate with maximum efiiciency. Itis the gen-- eral object of the invention to provide a simple andeflicient means for removing moisture from fluids of the characterreferred to. I realize this object in and through the constructionillustrated in the drawings forming part hereof, wherein Fig. 1represents aperspective view of a fluid 'tlrying device constructed inaccordance with my invention; Fig. 2 an enlarged vertical sectional viewthrough such device; and Figs. 3 and 4 sectional details correspondingrespectively to the lines 3-3 and 4- .1: of Fig. 2 and looking in thedirection of the arrows. 4

Describing by reference characters the various parts illustrated herein,1 denotes an outer cylindrical casing having a bottom 2 which isdownwardly inclined from the cy lindrical side wall of the casing to thecentral portion of such bottom where a pet cock 3 is provided for thepurpose of withdrawing water, or other liquid, from time to time. At itsupper end the cylindrical wall 1 is flanged outwardly, as shown at {1,and this flange has secured thereto a head 5, bolts 6 and a clampingring 7 being employed for the purpose of securing, the flange and headtogether. The head 5 is provided with a central aperture into whichthere is threaded a pipe 8. Projecting downwardly from the head andpreferably cast integral therewith is an annular flange 9 to the outersurface whereof there is secured a cylindrical wall 10 which extendsdownwardly within thp enc whereof is spaced from the bot-tom 2 of saidcasing, the parts being so arranged as to provide an annular spacebetween the parts 1 and 10.

In the operation of the device shown here-r in, the air or other fluidto be dried is discharged tangentially into the upper end of the annularspace between the casing 1 and the wall 10 and in a direction to impartahelical movement to the fluid. For the purpose of realizing thisresult, a pipe 11 is shown as discharging into a passageway formed inand preferably integral with the head This passageway, indicated at 12,is provided in a helical projection 13 at the top of the head 5 andpreferably formed integral therewith, the head being recessed asindicated at 13 so that the passageway is,

formed in part between the upper and the lower surface of the headproper. It will be observed that the" passageway 12 is of lesscross-sectional area at the discharge end thereof than at the inlet endthereof, whereby the fluid to be dried is discharged into the upper endof the annular space between the parts 1 and 1 0 at a high velocity, theinclination of the passageway and the arrangement of the parts 1 and 10being such that the fluid is given a helical direction during itspassage through such annular space, as indicated by the arrows on Fig.2. Because of this whirling action, any moisture in the fluid will beseparated therefrom by centrifugal action and will accumulate upon thecasing wall 1 from which it will drain down the inner wall of suchcasing and collect within the bottom 2, whence it may be removed fromtime to time by the pet cock 3. When the whirling fluidreaches thebottom of the cylindrical wall 10, it will ascend within such wall at arelatively low velocity and passes through the tube 8 to the point ofuse.

By the construction described, it is pos sible', througha comparativelysmall and inexpensive device, to effectively dry a fluid of thecharacter referred to and render it capable of employment asan impellingagent for sand as well as for other uses which will sug est themselvesto those skilled in the art.

aving thus described my invention, what I claim is .1. In a centrifugalair drier, the combination of an outer cylindrical casing having aclosed bottom, an inner cylindrical casing having its lower end spacedfrom the closed bottom of the outer casing and forming an annularpassage with such outer casing, a.

head common to both of said casin s, said head having a central outlettheret rou h communicating with the inner casing, an a helical"passageway for air formed therewith, the inner and outer walls of saidpassageway extending bodily around the said outlet and said passagewaybeing inclined toward and communicating "at its delivery end with saidannular passage; whereby a helical course will be imparted to the fluidin the passageway in said head and in the annular passage formed betweenthe inner and outer casings.

2= In a centrifugal air drier, the combination of an outer cylindricalcasing having a charging into the annular passage through 30 anelongated port. a

In testimony where0f, I hereunto afiix my signature.
